Chirurgische Nadel mit DrainageschlauchSurgical needle with drainage tube
Um den Heilungsprozess bei Operationswunden möglichst zu beschleunigen, ist es bekannt, dass Drainageschläuche, kurz Drains genannt, in die Wunden eingeführt und zur Absaugung von Wundsekret an einem Saugdrainageapparat angeschlossen werJen. Das eine Ende des Drain führt man mit einer chirurgischen Nadel, an deren stumpfen Ende er befestigt ist, aus der Wunde heraus. Es sind bisher Nadeln bekannt, an welchen der Drain lösbar befestigt ist. Aus Gründen der Sterilität ist es unbedingt erforderlich, diese Nadeln nach dem Gebrauch wieder zu sterilisieren, falls man sie nochmals verwenden will. Da aber aus Sicherheitsgründen zu empfehlen ist, jede Nadel nur einmal zu gebrauchen und dann wegzuwerfen, ist man davon abgekommen. Bei den herkömmlichen, lösbar mit dem Drain verbundenen Nadeln bestehtIn order to accelerate the healing process of surgical wounds as much as possible, it is known that drainage tubes, for short drains called, inserted into the wounds and used to suck out wound secretions connected to a suction drainage device. That one end of the drain is passed out of the wound with a surgical needle with the blunt end attached. There are previously known needles to which the drain is releasably attached. For reasons of sterility it is absolutely necessary to sterilize these needles again after use, in case one wants to use them again. But there for security reasons it is recommended to use each needle only once and then throw it away if you have lost it. Both conventional needles detachably connected to the drain

jedoch immer noch die Gefahr, dass aus Unachtsamkeit oder sonstigen Gründen eine Nadel ein weiteres Mal verwendet werden könnte. Dies würde schwerwiegende Polgen nach sich ziehen.however, there is still the risk that a needle will be used again due to carelessness or other reasons could. This would have serious consequences.
Die vorliegende Erfindung hat es sich daher zur Aufgabe gestellt, solche Irrtümer von vorneherein auszuschliessen. Erfindungsgemäss wird diese Aufgabe durch eine chirurgische Nadel mit einem Drainageschlauch dadurch gelöst,dass die Nadel an ihrem einen Ende ein im Längsschnitt sJlgezahnförmiges Anschluss-Stück aufweist, auf welchem der Drainapeschlauch unlösbar sitzt, wobei das Anschluss-Stück zwischen dem Ende des Nadelschaftes und einer ersten Sägezahnflanke einen zylindrischen Teil besitzt und der Aussendurchr.esser des auf dem Anschluss-Stück sitzenden Abschnittes des Drainageschlauches kleiner als der Durchmesser des Nadelschaftes ist.The present invention has therefore set itself the task of eliminating such errors from the outset. According to the invention, this object is achieved by a surgical needle with a drainage tube in that the needle at one end there is a connecting piece which is shaped like a longitudinal section has, on which the drainage tube is inextricably seated, the connecting piece between the end of the Needle shaft and a first saw tooth flank a cylindrical Part and the outer diameter of the section of the drainage hose sitting on the connection piece is smaller than the diameter of the needle shaft.
Nachfolgend wird anhand der beiliegenden Zeichnung ein Ausführungsbeispiel einer erfindungsgemässen chirurgischen Nadel näher erläutert. Die einzige Figur der Zeichnung stellt eine Nadel mit einem auf ihr befestigten Stück eines Drains dar.An exemplary embodiment of a surgical device according to the invention is shown below with reference to the accompanying drawing Needle explained in more detail. The only figure in the drawing represents a needle with a piece of one attached to it Drains.
Eine chirurgische Nadel weist einen geraden oder wie in vorliegenden Falle einen leicht gebogenen Schaft 1 auf, der an einem Ende zu einer Spitze 2 ausläuft. Das andere Ende der Nadel weist ein im Durchmesser verengtes Anschluss-Stück 3 auf, welches im Längsschnitt eine s£gezahnartige Form besitzt, wobei sich die steileren Flanken der Sägezähne auf der dem Nadelschaft zugewandten Seite befinden.A surgical needle has a straight or as in present case on a slightly curved shaft 1, which ends at one end to a point 2. The other end the needle has a connecting piece 3 which is narrowed in diameter and has a tooth-like shape in longitudinal section, the steeper flanks of the saw teeth being on the side facing the needle shaft.
Auf diesem Sägezahnprofil sitzt ein Drainageschlauch 4 satt auf. Sein äusserer Durchmesser ist dabei etwas kleiner als der des Nadelschaftes in unmittelbarer Drain-Nähe. Der innere Draindurchmesser entspricht dem kurzen zylindrischen Teilstück zwischen dem Schaft 1 der Nadel und dem ersten Sägezahn des Anschluss-Stückes 3·A drainage hose 4 sits snugly on this sawtooth profile on. Its outer diameter is slightly smaller than that of the needle shaft in the immediate vicinity of the drain. The inner drain diameter corresponds to the short cylindrical section between the shaft 1 of the needle and the first saw tooth of the connection piece 3 ·

Durch diese Anordnung und Dimensionierunp; ist es möplich, den Drain dermassen satt auf das Anschluss-Stück aufzuziehen, dass er auch unter grösster Kraftanwendung nicht mehr von der Nadel getrennt werden kann. Dadurch steigt einerseits der Sicherheitsfaktor, dass sich der Drain beim Einziehen nicht unbeabsichtigt von der Nadel löst, und andererseits wird dadurch eine Wiederverwendung der Nadel verunmöp.licht. Zum Anschluss an einen Saugdrainageapparat muss nämlich der Drain knapp vor der Nadel abgeschnitten werden, so dass ein kleines Schlauchstückchen auf dem Anschluss-Stück verbleibt und ein neuerliches Festmachen eines anderen Drains verhindert.Through this arrangement and dimensioning; is it possible Pull the drain so full on the connection piece that it can no longer be removed from the Needle can be separated. On the one hand, this increases the safety factor that the drain does not move when it is pulled in unintentionally detaches from the needle, and on the other hand this makes it impossible to reuse the needle. To the Connected to a suction drainage device, the drain must be cut off just in front of the needle, so that a small The piece of hose remains on the connection piece and prevents another drain from being fastened again.
